OpenSPOT2 on SharkRF IP Connector Server - "got nak" - unable to connect

johndball

Could be old device issues, but if anybody is able to help here.

I just built a fresh SharkRF IP Connector Server. There is NOTHING between the OpenSPOT2 and the Server - no firewalls, no subnets, nada.

I'm unable to get the OpenSPOT2 to connect to the server. The log file shows:

09:41:21 srfipconn-client: initializing connection
09:41:21 srfipconn-client: connecting
09:41:21 srfipconn-client: sending login
09:41:21 srfipconn-client: sending auth
09:41:21 srfipconn-client: got nak
09:41:21 srfipconn-client: init reconnect

I set the config file with the following parameters:

{
  "port": 65100,
  "ipv4-only": 1,
  "bind-ip": "0.0.0.0",
  "max-clients": 1000,
  "max-api-clients": 100,
  "client-login-timeout-sec": 10,
  "client-timeout-sec": 30,
  "client-status-syslog-interval-sec": 30,
  "server-password": "va2022!",
  "auth-fail-ip-ignore-sec": 5,
  "pidfile": "srf-ip-conn-srv.pid",
  "api-socket-file": "/var/sharkrf/srf-ip-conn-srv.socket",
  "server-name": "SharkRF IP Connector Protocol Server",
  "server-desc": "www.johndball.com | www.kn4ola.com",
  "server-contact": "kn4ola@kn4ola.com",
  "allow-simultaneous-calls": 0,
  "banlist-file": "",
}

The OpenSPOT2 is configured as such:

Server address: 10.24.119.212
Port (UDP): 65100
ID: 0
Server password: va2022!
Callsign: KN4OLA
Keepalive: 5
RX timeout: 30
Connect retry: 6

It now takes me at least four attemps to connect OS4 to openspot4/local
SERVER NOT FOUND message.

Channels 1,6, and 11 tried.
Open spot is less than 10 inches from wifi router.
Tried two other browsers.
Re-Set modem. Re-set OS4. Reset PC.
No other issues with internet.
Rasberry pie conects first time every time.

This needs to be fixed.

@johndball Make sure you use jsmn commit 732d283 when compiling the server, and compile the debug build as the optimizations in recent GCC versions break SHA256 calculations.

@EdEdward Please don't hijack other user's thread, especially if the thread is tagged for openSPOT2 and you write about your openSPOT4. Use https://sharkrf.link/ to open the web interface of your openSPOT4.

I followed this Github: https://github.com/sharkrf/srf-ip-conn-srv

git clone https://github.com/zserge/jsmn
cd jsmn
git checkout 732d283ee9a2e5c34c52af0e044850576888ab09

Compile the debug build as the optimizations in recent GCC versions break SHA256 calculations

I don't know what that means and I need a little hand holding on this one...
I can see the OpenSPOT2 and the server communicating in the logs, just not authenticating. So I think you're on to something about the calculations, but not sure what I need to do at this point.

Run build-debug.sh instead of build-release.sh
